Public Health England has published data relating to resistance to more than one antibiotic among Acinetobacter baumannii and A. lwoffii bacteraemia.
the
incidence rate of Acinetobacter spp.
bacteraemia has decreased over the eight year period from 2008 to 2015 the
country with the highest incidence rate in 2015 was Northern Ireland (1.6 per
100,000 population) within England, the English region with the highest
incidence rate was Greater Manchester (1.8 per 100,000 population), while
Anglia and Essex had the lowest (1.0/100,000);
Infants
have the highest rate of Acinetobacter
spp. infection (8.2 per 100,000 population);
Individuals
aged 75 years and over also having a relatively high rate (3.7 per 100,000
population), variation is noted by Acinetobacter
species in 2015, 50% percent of neonatal Acinetobacter spp. bloodstream infections occurred in infants less
than 7 days old (18/36) there were more Acinetobacter
spp. reports for females than males with rates of 1.4 and 1.3 per 100,000
population respectively (432 and 381 reports respectively);
Organisms
A. lwoffii and A. baumannii continue to be the most common species of Acinetobacter in 2015 from blood
isolates (38% and 20% respectively), accounting for over half of all isolates
the level of resistance to colistin has fallen to a five year low (2%);
However
the proportion of Acinetobacter spp.
bacteraemia tested for colistin susceptibility remains below 13% in England,
Wales and Northern Ireland in 2015 resistance to a carbapenem (meropenem and/or
imipenem) has decreased over the last 5 years a reduction in the proportion of
resistant Acinetobacter spp
bloodstream isolates was noted between 2011 and 2015 for each of the following
antimicrobials: gentamicin, ciprofloxacin, tobramycin and amikacin of 42
isolates of A. baumanii (29) and A. Iwoffi (13) tested, there was no (0%)
multidrug resistance to gentamicin, ciprofloxacin, carbapenem and colistin.
